Gold Catfish in Amazon

To unlock the Gold Catfish, you must first find the Servants Ring that is located between the waterfall and elsewhere in Twilight Temple. When you find the Servants Ring, GG will appraise it before you have a chance to call Nancy. He will tell you it is worth nothing. Then, return to the Amazon where you found the Giant Catfish. A cutscene will begin, and you will have a chance to give the fish your ring at the end. Select "Yes", do some exploring or something else, then return to the boat. During your next dive you will return to the catfish and another cutscene will reveal that the catfish is now a Gold Catfish.

Blue Cliffs

At a certain point you will be asked to go to the Blue Cliffs, which are located in the deep area of grid marks A and B 8. You must swim around for a bit towards the bottom (almost to where you cannot go any farther). This might require a few attempts. It is recommended you try grid mark B8 and swim towards grid mark A8 first at various depths.

Finding Lower Ice Cave 3

Find the fissure at C8, and follow it down so you do not have to measure meters versus feet or get confused.

Finding Pelago Crocodile

Look through the telescope on the morning before the full moon to see the Pelago Crocodile. Note: Keep entering the cabin repeatedly to advance time until sunrise.

Finding nearby fish

If you complete at least 25% of the map, sometimes there will be an icon above the grid view icon of a magnifying glass with a picture of a fish. Select the icon, and the arrows (if allowed) to see nearby fish or fish you have yet to discover. These will have "???" in the name. After you discover the fish and animal, they will also appear in the encyclopedia once you select its image. This is very useful when you need to take photos of a fish.

Nocturnal fish

Some fish only appear at night. For example, there is a fish in Cicero Straits that blends in with a shipwreck, and it looks like a piece of wood breaking apart from the boat. Use the fish icon on the map to find it.

Salvage Request

Salvage requests do not require use of you equipment. Jean-Erics request will appear in a red glow and Gestan Grey's will appear in an orange glitter glow.

Deep Sea Dive

For the Deep Sea Dive, after you complete the mission of retrieving the bag from the sub, your portable air tanks will disappear. However, you will not need them after this is done.

Okeanos Guardian in Cavern Of The Gods

When you encounter the Goblin Sharks, scan the largest shark in the Cavern Of The Gods.

Singing Dragon in Cavern Of The Gods

Get past the Giant Goblin Shark in the Cavern Of The Gods, and the Singing Dragon, a white whale, will appear.

Albino Bottlenose Dolphin in Ciercos Strait

Train your dolphin until it reaches level 2. Meet Finly the dolphin trainer, and invite him to see your dolphin show. He will tell you to go to Ciercos Strait to find a white dolphin. Go there, and rescue it from the shark.

Sea Serpent in Ciercos Strait

Sell at least three maps, and Oceana will tell you about a shadow on the map of Ciecrocos Strait. Keep asking Oceana about it, and she will tell you where the Sea Serpent can be found.

Apollo the Ocean Sunfish in Deep Hole

Go to Deep Hole at night to find Apollo, a large golden ocean sunfish, above the Mouth of Truth.

Secret cave in Deep Hole

The secret cave in the Deep Hole area is located in the middle of the Deep Hole itself. You must have your dolphin by you and press A when instructed to open it.

The Triton Ring can be found near the Ribbon Moray Eel in the Deep Hole. The Moray Eel looks like a Blue Tang. Note: The Multisensor is required to find it.

Legendary Leatherback Sea Turtle in Gatama Atoll

Have Snorkel on the island, and look for him by the bonfire. Pet him to get information about a strange moving island in Gatama Atoll. Investigate that area to find the legendary Leatherback Sea Turtle.

Three fish to heal locations in Gatama Atoll

During your return to Gatama Atoll, you must locate and heal (with your pulsar) three fish: a Manta Ray, a Humphead Wrasse, and a Manta Whale. They are located at grid marks C3, G2, and E8. If you do not know what you are looking for, the best thing to do is swim to these locations and discover them first. Make sure your tank is upgraded or you will not have enough air to finish the tasks. You will get three tries before you must leave the area and return later to try again.

Finding Snorkle in Gatama Atoll

Snorkle is a lost puppy which you stumble upon. He can be found at Gatama Atoll on the island at grid mark H1. Note: You must surface in more than one location in some islands to cover them all.

Eggs in Gatama Atoll

Fish eggs will begin appearing in certain locations on the reefs after spending awhile in Gatama Atoll.

Tour for White Grouper in Valk Castle

The White Grouper you must find a few times is in the Castle Gallery. This is the first place you find the False Killer Whale.
